What we researched for this specific generation: where an enclosure actually fits, what the factory speakers are, how the factory audio is wired, and which real builds and commercial products exist for it. Confidence badges say how well each figure is sourced — this is research, not manufacturer spec.
Body styles covered: 4-Door SUV, 3-row, ESV extended-length
These are researched envelopes, not a guarantee. Measure your own vehicle — the numbers here tell you what to expect, not what you have.
| Location | cargo hold, rear seats up |
|---|---|
| Outer bounding box | 49"W x 15"H x 10"-13"D (rear seats up) |
| Known obstructions | A shallow (~4" deep) space exists under the floor panel specifically suited to thin-driver subs, distinct from the main cargo volume above it. |
Suggested configurations for this vehicle, not prescriptions. Run the numbers in the Box Builder before you buy anything.
| Subwoofers | 1x thin-driver, shallow under-floor mount (real named product: Trulli TD10S ThinDriver) |
|---|---|
| Box type | n/a — thin-driver, shallow mount |
| Location | under floor panel, ~4" deep space |
| Subwoofers | 1x10" or 1x12" sealed, custom-built, disabling ANC first and using the confirmed wire-color reference |
|---|---|
| Box type | sealed, custom |
| Location | cargo hold |
Sizes and depths below are what research turned up for this generation. Confirm against your own vehicle before cutting or ordering — trim levels vary.
| Factory speaker size | 6.5" woofer, confirmed real — front doors are a true 3-way component setup: woofer + midrange + tweeter all mounted in each front door, PLUS a separate 1" tweeter in each A-pillar, PLUS a 3.25" 'Twiddler' neodymium mid/high-range driver in the center of the instrument panel. This is a genuinely rich, multi-location system, not just a 2-speaker-per-door setup. |
|---|---|
| Known obstructions | None specifically documented |
| Adapter bracket needed | Real, named commercial A-pillar speaker pod product confirmed specifically for THIS generation (2015-2020): 3.5in and 2in pod options from CustomSpeakerPods.com. |
| Tweeter | A-pillar (confirmed, real named speaker-pod product exists for this exact location/generation) AND door-mounted (confirmed as part of the 3-way component door set) — two real tweeter locations, not one. |
| Midrange | Center of the instrument panel (Twiddler) AND door-mounted (part of the 3-way component door set) |
| Factory speaker size | not independently confirmed by exact size |
|---|---|
| Known obstructions | None specifically documented |
| Adapter bracket needed | unconfirmed |
| Tweeter | n/a — not confirmed |
| Midrange | n/a — not confirmed |
| Factory amp / premium audio | Bose premium system (this generation): factory 6" single-voice-coil subwoofer mounted in the CENTER CONSOLE — a genuinely unusual factory sub location, not the cargo area. Real, specific replacement wiring confirmed: at the plug nearest the rear of the car, the subwoofer+ signal runs on a Blue-with-White-stripe wire, subwoofer- on a Light-Green-with-Black-stripe wire — a real, exact, reusable wiring reference. Real owner caution: factory Bose amps exist but 'aren't ideal' for pairing with aftermarket head units or speakers. |
|---|---|
| Adding subs without a head-unit swap | Confirmed, but with a real, important prerequisite: adding an aftermarket amplifier, processor, or subwoofer requires DISABLING the factory Active Noise Cancellation (ANC) system first — the same ANC-vs-audio-upgrade conflict pattern already confirmed on our Buick Envision entry. |
| Head unit | No replacement needed |
Real, specific cargo dimension confirmed: 49"W x 15"H x 10"/13"D with the rear seats up — genuinely generous room for a large subwoofer/box combo, among the largest confirmed cargo figures. A real, genuinely clever alternative approach: a professional installer identified a small, shallow (~4" deep) cargo space under the floor panel specifically suited to thin-driver subwoofers (real named product: Trulli TD10S ThinDriver) — a real, low-profile option distinct from a full box build.

Measure your own vehicle. Trim levels, factory subwoofer options, and mid-generation changes all move these numbers, and a box cut to a researched figure that does not match your truck is wasted wood. Where a badge reads Unconfirmed, treat the value as a starting point for your own measurement, not as an answer.
